yeah mines under the radio too, but i have a cd changer in the trunk so its kinda weird lol.
what DID work for me the first time i tried it was
take your car to a heavy car parking structure, turn it off for 15 minutes, then turn it on and wait for the radio to reset.
apparantly bein in the car park blocks some sort of connection with something and lets things boot up.
it worked for my radio, and clock but only temporarily. eventually it fixed itself
I didnt have to.
